Two interesting discoveries this weekend.
1) Does S&B sometimes make straight-up copper casings for 9mm sometimes? After a round of of wet tumbling, look at these 3 S&B casings. 2 of them are fine, and as normal. Yet 1, is copper, identical in color to copper piping (the picture only comes out so good). 
I've never seen that before, except in copper washed steel casings (which are always Berdan primed, and this is Boxer). 2) GFL brass has the worst off-center flash holes I've ever seen in my life. Look at this! 
Just a headsup, because I almost broke a decaping pin on this, since it's so off center. |
| It's not copper but steel. As I understand it, copper binds to brass better than steel itself, so they copper plate them and then brass plate. GFL brass has that reputation and it's caused some press manufacturers to change their warranty policies because of these inconsistencies in brass cases. |

I just tested, and it is indeed a steel casing. I did not know they made steel 9mm. Now I do. Thanks. |

Most of my Perfecta 5.56 brass has way off-center flash holes. PMC 5.56 has the tightest crimps. Both are heavy at about 98-102gr after processing. Dang, that is PMP kind of heavy. I have 500 to 1K GFL cases a friend gave me, looks like they are going into the case of last resort. |
